The settlement or gift deed are immediate transfer of properties in favor of the beneficiaries/donees.

When you inherit property, the first thing you must do is to transfer the title of the property to your name. You can do this by a process called 'mutation of revenue records.' You would need either a copy of the Will or in absence of a Will a legal heirship certificate issued by Tehsildar/revenue department.
After having transferred the property in your name, if you want to transfer the property to your spouse or child you can follow the same procedure that is required to be followed by any other citizen of India. In addition you may produce the certificates that would be required to establish your status and your wife's status, but it is not as tedious as had been misinformed by the person who you contacted in this regard,.
NRIs should consider the services of a local lawyer to handle property transfer matters for them.
